Abstract
The present invention relates to a combustion resistant down pipe preventing climbing up for the external wall of construction, which is formed by sheathing and connecting a plurality of pipe joint bodies (2). A connecting point has no steps and is smooth. Each section of pipe body (2) has the structure that fixed lugs (1) which are integrally connected with the upper part and the low part are respectively arranged on the upper part and the lower part, and an internal sinking insertion opening (3) is arranged on the upper end. Each section of pipe body (2) has the shape that a back surface (namely the surface attached to a wall surface) is a flat bottom surface, and a lateral surface (namely a portion is projected out of the wall surface) is cambered. The present invention has the advantages of climbing prevention, combustion resistance, light weight, material saving, low cost, convenient production, convenient transportation, high safety, etc. and belongs to a new product for replacing the existing down pipe.
Description
The present invention is that fire-retardant leader is climbed in a kind of resistance of used for building exterior wall.
At present, depending on the leader of the discharging rainwater on civilian and the industrial construction exterior wall, generally all is that cast iron is made, and the cross section of this pipe fitting is circular, coupling part has the thick step of 10mm approximately, and the problem that this structure is brought mainly is to help human body to depend on upwards climbing of tube wall.Condition easily objectively is provided necessarily for pivot frame people chamber stealer.Bring great harm to social public security, in addition, leader could be installed after all will burying the iron fastener underground in the civil engineering stage.Therefore giving to install also makes troubles.Application CN2108765V discloses a kind of Plastic down pipe joint, comprises the pop-up mouth that is integrated, and lower inserting part and solid empty ear can conveniently connect leader, make the connection place not fragile, but still can not overcome the shortcoming that leader is easily climbed up by holding on to.
The purpose of application provides a kind of skin leader, makes the people be difficult for upwards climbing up by holding on to along body, and avoids installing connector, simplifies and installs, and is sturdy and durable.
The object of the present invention is achieved like this, (it is made up of some pipe joint bodies that mutual insertion connects, the structure of every pipe joint body is, its upper and lower part respectively is provided with the fixedly ear that is connected as a single entity with it, the upper end is provided with for its pipe joint body lower end and inserts the interior heavy socket that connects, thereby it is sliding to make 2-section pipe body junction not have step peace lay the grain, and the back side (being wall covering surface) is flat bottom surface, and side (being the protruding wall face portion) is arc shape.
The cross section of body is semicircle or circle of contact shape or half elliptic, and this kind shape makes body have resistance and climbs effect.
Above-mentioned body can adopt cast iron with fire resistance or plastics or glass-reinforced plastic material to make.
The present invention has the following advantages than prior art:
The one, resistance is climbed, this is because the body planar section is attached on the skin, outside one side is the arc that is equal to or less than semicircle, and saved the connected body between the body, make the sliding no step of junction peace lay the grain of adjacent body, be unfavorable for stealer depend on tube wall on climb up by holding on to, thereby help safeguarding social public security.
The 3rd, to be convenient to produce and to install, this is because save and have step and must the pre-buried connecting piece that could install, and has adopted the cause of the fixedly ear that is connected as a single entity with body;
The 4th, after The selection of pipe plastics or the glass fiber reinforced plastic, not only weight lightens and can save the brushing paint operation, and is convenient to transportation and installation, and outward appearance is also beautiful.
In addition, because plastics or the glass fiber reinforced plastic making body selecting cast iron for use or have fire resistance, so help security against fire.
In a word, the present invention is a kind of product that can substitute the update of existing leader.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention;
Fig. 2 be among Fig. 1 A to schematic diagram;
Fig. 3, Fig. 4 are respectively B-B among Fig. 1, C-C sectional view.
As shown in Figure 1 and Figure 2: the present invention is made up of some pipe joint bodies 2 that mutual insertion connects.In every pipe joint body 2, its upper and lower part respectively is provided with the fixedly ear 1 that is connected as a single entity with it, and heavy socket 3, its back side (being wall covering surface) were flat bottom surface in its upper end then was provided with, and side (being the protruding wall face portion) then is arc shape.The cross section of this arc shape side is a semicircle (seeing Fig. 2, Fig. 3 Fig. 4) or less than the circle of contact or the half elliptic of semicircle.
The present invention can be cylinder iron or plastics or glass-reinforced plastic material with fire resistance make.If when making of glass fiber reinforced plastic, fixedly the arcuate flanks of ear 1 is affixed on the inwall of body 2, pastes one deck frp lining 4 again over, makes it closely to link to each other (asking for an interview Fig. 4).The fixedly ear 1 usefulness reinforced plastic of this moment is made.
During installation, earlier the plane with a pipe joint body 2 is affixed on metope, again with nailing fixedly ear 1 enter within the walls, this joint (first segment) body is adorned on the wall securely.Then, the lower end of another pipe joint body 2 interior heavy socket 3 along aforementioned tube body 2 is inserted, behind the position that falls, this moment, junction was upper and lower as integral body, smooth smooth; Passing fixedly with nailing again, ear 1 is adorned on the wall this joint (second joint) body securely.Repeat above action, till final section body 2 is fixed on the wall.
Claims (4)
1, fire-retardant leader is climbed in a kind of resistance of used for building exterior wall, interlock by some pipe joint bodies (2) and to form, the structure of every pipe joint body (2) is, its upper and lower part is provided with the fixedly ear (1) that is connected as a single entity with it, the upper end then is provided with interior bell and spigot (3), the back side that it is characterized in that body is flat bottom surface, and the side then is an arc shape.
2, leader according to claim 1, the cross section that it is characterized in that described body are semicircle or circle of contact shape or half elliptic.
3, leader according to claim 1 and 2, it is characterized in that described body cylinder iron or plastics make.
4, leader according to claim 1 and 2 is characterized in that described body makes with glass-reinforced plastic material.
